I lost(丢失) my schoolbag on the playground. It's blue. There are some books, a pencil case and my keys in it. My friend Lingling lost hers, too. It's pink. There are some books, her student card and some pens in it. Daming lost his coat in the library. His coat is yellow. His name is on it. My name is Mike. Please call me at 61207896.
